Wendi Deng, a businesswoman and mother of two is perhaps best known for the slap that protected her media mogul husband, Rupert Murdoch.

In July 2011, Deng lunged at a protester who was advancing on Murdoch with a shaving cream pie during a UK parliamentary hearing on allegations of phone hacking by Murdoch's media company.

The Twitterverse lit up with chatter about the incident and bloggers in her native China largely applauded her.

But that one instinctive, protective swipe could not completely remove suspicions about the 44-year-old woman's marriage to 82-year-old Murdoch. So often, the age difference, his riches and her beauty were mentioned alongside each other.

Deng first made waves when she married Murdoch in 1999, shortly after he divorced his wife of more than 30 years, Anna Torv Murdoch Mann.

Deng has come a long way, coming from a small town in China, the daughter of a poor factory engineer.

Her marriage to Murdoch wasn't her first.

She married the man who, with his then-wife, sponsored her for a student visa in the United States during the late 1980s. She eventually secured a "green card" to stay permanently in the United States, but her first marriage was short-lived.

Despite her moments in the spotlight and her pre-marriage career in Murdoch's empire, not much is known about Deng.

She sits on the board of advisers at the Yale School of Management, her alma mater. She is listed as a co-founder of Big Feet Productions and is also co-producer of the movie, "Snow Flower and the Secret Fan."
